(E) 5 European foreword This document (EN 12467:2012+A2:2018) has been prepared by Technical Committee CEN/TC 128 “Roof covering products for discontinuous laying and products for wall cladding”, the secretariat of which is held by NBN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by October 2018, and conflicting national standards shall be withdrawn at the latest by January 2020. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This document includes Amendment 1, approved by CEN on 24 November 2015 and Amendment 2, approved by CEN on 9 November 2017. This document supersedes #EN 12467:2012+A1:2016$. The start and finish of text introduced or altered by amendment is indicated in the text by tags !" and #$. !In comparison with EN 12467:2004, the following sections in EN 12467:2012 had been changed or added:" 3.9, 3.10, 4, 5.1.1, 5.4.3, 5.4.4, Table 7, Table 8, 7.3.2, 7.3.2.4.2, 7.3.3.3, 7.3.3.4, 7.3.7, 7.5.2.2 and Annex C.
Annex ZB concerning the EC Directive 76/769/EEC !had been deleted". This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. For relationship with #EU Regulation No 305/2011", see informative Annex ZA, which is an integral part of this document. A distinction !had been made" between product appraisal (type tests) and factory production control requirements (acceptance tests). The performance of a building part constructed with these sheets depends not only on the properties of the product as required by this document, but also on the design, construction and installation of the component as a whole in relation to the environment and conditions of use. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

(E) 7 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 acceptance test test to establish whether a batch of sheets conforms to a specification and which is performed on samples drawn either from continuous production or from a consignment Note 1 to entry: Test methods, specifications and limit values are specified in this document. Sampling levels and acceptance criteria are specified in 6.3.2. 3.2 initial type test test carried out to demonstrate conformity with the requirements of this document or for the approval of a new product and/or when a fundamental change is made in formulation and/or #manufacturing process$, the effects of which cannot be predicted on the basis of previous experience Note 1 to entry: The test is performed on the as delivered product, but is not required for each production batch. 3.3 acceptable quality level (AQL) quality level which in a sampling plan corresponds to a specified, relatively high probability of acceptance Note 1 to entry: It is the maximum percent defective (or maximum number of defects per 100 units) that for purposes of sampling inspection can be considered satisfactory as a process average. Note 2 to entry: A sampling scheme with an AQL of 4 % means that batches containing up to 4 % defective items have a high probability of acceptance. 3.4 apparent density density based on the external dimensions of the sample to calculate the volume Note 1 to entry: This is an average density of material and pores. 3.5 as delivered same condition as the producer intends to supply the product after completing all aspects of the process including maturing and, when appropriate, painting 3.6 upper face face normally exposed 3.7 under face reverse of upper face 3.8 textured sheets sheets which have a relief pattern embossed or applied as a coating on their upper face before delivery SIST EN 12467:2013+A2:2018

The cement shall comply with EN 197-1 or with technical specifications relevant in the country of use. #The cement shall comply with EN 197-1 or an agreed technical specification relevant in the country of use provided the cement compound composition is in accordance with EN 197-1.$ This European Standard covers fibre-reinforced cement flat sheets of type NT. The reinforcing fibres shall be one or more of the following forms: — discrete elements randomly dispersed; — continuous strands or tapes; — nets or webs. Process aids, fillers, aggregates and pigments may be added. 5.1.2 Appearance and finish The exposed face of the sheets can be with or without texture. The sheets can be coloured or left in their natural colour. The sheets can also receive adherent coloured or uncoloured coatings on their surface. Variations of the surface appearance which do not impair the fitness for purpose of the sheets are permitted. The sheets may be supplied with holes for fixing and/or cut to size.

EN 12467:2012+A2:2018 (E) 10 5.2 Classification 5.2.1 General Sheets covered by this document are divided into: — four categories in accordance with their weather resistance (see 5.2.2 to 5.2.5); — five classes in accordance with their bending strength (see 5.4.3); — two groups of sizes in accordance with their method of installation (see 5.2.6); — two levels in accordance with their dimensional tolerances (see 5.3.4). Type tests for each category are specified in Table 7. 5.2.2 Category A Sheets which are intended for applications where they may be subjected to heat, high moisture and severe frost. 5.2.3 Category B Sheets which are intended for applications where they may be subjected to heat, moisture and occasional frost, e.g. where they are either protected from or not subjected to severe weathering conditions. 5.2.4 Category C Sheets which are intended for internal applications, where they may be subjected to heat and moisture, but not to frost. 5.2.5 Category D Sheets for rigid underlayer applications. 5.2.6 Groups of sizes 5.2.6.1 Small size sheets Sheets for which the method of installation includes horizontal overlap. Their dimensions are generally such that their area is < 0,4 m2 and have a length/width relation
¶ 3. 5.2.6.2 Large size sheets Sheets which do not correspond to indicators for small size sheets. Large sheets may be declared as "small size sheets" provided tolerances for small size sheets apply and are specified
